X+24=35 how to solve this
timama [110]

Answer:

X = 11

Step-by-step explanation:

Simplifying

X + 24 = 35

Reorder the terms:

24 + X = 35

Solving

24 + X = 35

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-24' to each side of the equation.

24 + -24 + X = 35 + -24

Combine like terms: 24 + -24 = 0

0 + X = 35 + -24

X = 35 + -24

Combine like terms: 35 + -24 = 11

X = 11

Simplifying

X = 11

Given f(x) = x+2 and g(x) = x-4 solve for (fg)(x)
kirza4 [7]

Answer:  f(g(x)) = x - 2

<u>Step-by-step explanation:</u>

f(x) = x + 2            

g(x) = x - 4

f(g(x)) = f(x - 4) = (x - 4) + 2        <em>replaced x with x - 4</em>

                       = x - 2                 <em>simplified</em>

given a rectangle of length a and width b if A and B are both rational numbers would the perimeter be irrational or rational? Gi
Kitty [74]
The perimeter would be rational due to both the width and length being rational numbers. A rational number is a number that can be written as a fraction such as 8 it can be written as 8/1, but a irrational would be a decimal number which in this case there would be none because both length and width is rational number. For example, Lets say the width is 8 and the length is 10. once both are written into fraction form such as 8/1 and 10/1 we add them to get a perimeter of 18.
Hope this helps! <span />
